I think the two men are very different, but with common aspects to their characters.
Ross is a caring family man who is more than able to put himself in someone else's position, and see when he has overstepped the mark, and retract and apologise appropriately, as he has done ion this instance.
Brand is an immature individual who exhibts the self-centered attitudes of his (largely) teenage / early twenties single audience and sees controversey as an acceptance and endoresement of his 'cutting edge humour'.
Where the two come together is with a tendency to be pushed beyond reasonable boundaries in similar company - as in this instance where they have seemingly forgotten that they are making a radio show, and simply wound each other up like a couple of schoolboys.
The fault lies with the show's producer and the 'senior executive' who have sanctioned broadcast of an item that has obviously gone well beyond acceptable behaviour and broadcast standards - had it been dumped, no-one who have known anything of what was an immature time between two men who should be old enough to know better.
Ross, tho his credit, has written a personal apology to Mr Sachs, Brand has delivered an 'apology' over the air - assuming quite wrongly that Mr Sachs would be within a hundred miles or a radio on which he is broadcasting - and then swerving into some mindless nonsense about the Holocasut, which given Mr Sach's ethnicity, simply adds insult to injury.
I await developments with interest.
